Sahih Muslim 1424a
Abu Huraira (Allah be pleased with him) reported: I was in the company of Allah's Messenger (way peace be upan him) when there came a man and informed him that he had contracted to marry a woman of the Ansar. Thereupon Messenger of Allah ﷺ said: Did you cast a glance at her? He said: No. He said: Go and cast a glance at her, for there is something in the eyes of the Ansar.
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ يَزِيدَ بْنِ كَيْسَانَ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي، هُرَيْرَةَ قَالَ كُنْتُ عِنْدَ النَّبِيِّ ﷺ فَأَتَاهُ رَجُلٌ فَأَخْبَرَهُ أَنَّهُ تَزَوَّجَ امْرَأَةً مِنَ الأَنْصَارِ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ " أَنَظَرْتَ إِلَيْهَا " . قَالَ لاَ . قَالَ " فَاذْهَبْ فَانْظُرْ إِلَيْهَا فَإِنَّ فِي أَعْيُنِ الأَنْصَارِ شَيْئًا " .
